METHOD OF MAKING FRAMES FOR HARNE SS-BUCKLES.

EPEQIPICATION forming part of Letters Patent No. 369,430, dated September 6. 1887.

Application filed April 23, 1887. Serial No. 235,837. (No modeLl To all whom, it may concern:

Be it known that 1, WILLIAM B. BROOKS, residing at W'aterbury, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in the Method of Making Frames for Harness- Buckles; and I do declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to an improved method of making frames for harness-buckles, the ob ject being to produce with great economy over the old methods frames having tonguegnards and a tonguescat.

With these ends in view my invention consists in a method of making frames for harnessbuckles, consisting in stamping a frameblank out of sheet metal; then piercing out the center of such blank, and then developing tongue-guards and a tongue-seat, respectively, upon and in such pierced blank by subjecting the same to pressure between suitable dies, which also transform it into a buckleframe.

In the accompanying drawings, Figure 1 is a plan view of the blank in its first stage. Fig. 2 is a view thereof in central longitudinal section. Fig. 3 is a plan view of the blank after its center has been pierced out. Fig. 4. is a view of such pierced blank in central longitudinal section. Fig. 5 is a plan view of the buckle-frame developed from such pierced blank by subjecting it to pressure between suitable dies and showing the tongue-seat. Fig. 6 is a reverse plan view of such frame, showing the tongue-guards.

Fig. 7 is a view of the frame in central longitudinal section. Fig. 8 is a plan view of the completed buckle, and Fig. 9 is a view thereof in central longitudinal section.

The blank A is first died out from suitable wrought, sheet, or plate metal, and conforms in general outline to the edge ofa bnckleframe. The center of this blank is then pierced eaten a line conforming to the inner outline of a buckle-frame and the pierced blank B produced. This pierced blank is then subjected to pressure between highly'polished steel dies adapted to shape it, harden and polish it, and so develop the frame 0, having elevated tongueguards D D and a- (lepresscd tongue-seat, E, such guards and seat being produced by a suitable construction of the dies.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent. is-

A method of making harness buckle frames, consisting in first stamping out a blank from sheet or plate metal, then piercing out the center of such blank, and then developing tongue-guards and a tongueseat, respectively, upon and in such pierced blank bysubjecting the same to pressure between suitable dies, which also transform it into a buckle-frame, substantially as set forth.

In testimony wliereofl have signed this'specification in the presence of two subscri hing witnesscs.
